Why do people make the decisions they do? How can we detect if someone is lying? How can you break bad habits? Neuroscientists are searching for answers to these and many other complex questions within our brains, but quite often it's not as simple or clear-cut as it first may appear.
Advancements in science and academic research over the past few years relating to deception and lie detection have gone inward to the brain as well with the application of functional magnetic resonance imaging (fMRI), also known as brain scans. What these machines do is track blood flow to the brain. One of the recent findings in lie detection is that it that lying can be a more cognitively complex task than telling the truth, and that the brain must exert extra effort when telling a lie whereby causing certain regions of the brain that do more work to get more blood and light up during brain scans.
Sounds simple…maybe too simple. The Neuroscientist Molly Crockett thinks so too in the video below. What do you think?
